BF - Block of Memory Fill
3-8
3
If the upper address of the range is not on the correct boundary for
an integer multiple of the data to be stored, then data is stored to the
last boundary before the upper address. No address outside of the
specified range is ever disturbed in any case. The Effective
address messages displayed by the command show exactly where
data was stored.
Examples
Example 1: For this example, assume that memory from $20000
through $2002F is clear.
Because no option is specified, the length of the data field defaults
to word.
